1. Soda
Ash Features:
True specific gravity 2.**3 (*0°C), bulk density 0.*0min. Easily
soluble in water, Maximum solubility at *5.4°C. The aqueous
solution appears strong alkalinity. On exposure to air it easily
absorbs moisture, carbon dioxide, and gradually forms sodium
bicarbonate (caking soda)
2. Soda
Ash Usage:
1.The
manufacture of glass is one of the most important uses of sodium
carbonate. When it is combined with silica (SiO2) and calcium
carbonate (CaCO3) and heated to very high temperatures, then cooled
very rapidly, glass is produced. This type of glass is known as
soda lime glass.
2.
Soda ash also is used to clean the air and soften water.
3.
Manufacture of Caustic Soda and dyestuffs
4.
metallurgy (processing of steel and extraction of iron
etc),
5.
(flat glass, sanitary pottery)
6.
national defense (TNT manufacturing, *0% gelatin-type dynamite )
and some other aspects, such as rock oil refining, paper
manufacturing, paint, salt refining, softening of hard water, soap,
medicine , food and so on.
3. Soda
Ash Application:
Soda ash is one of the basic materials for chemical industry,
mainly used for metallurgy, glass, textile, dye printing, medicine,
synthetic detergent, petroleum and food industry etc.
